srEoIFIcATIoN fornng part of Letters Patent No. 735,478, dated August 4, 190s.

Application filed April 10, 1902.

To all whom it may concern l Be it known that I, GEORGE W. DUvALL, a

citizen of the United States of America, and a resident of Davenport, in the county of Scott and State of Iowa, have invented a certain new and .useful Improvement in Broom-Corn Out- 1 ters; and I do declare the following specificay tion, taken in connection with the drawings making a part of the same, to be a full, clear, and exact description thereof. A

My invention relates tobroom-corn cutters, and particularly to devices for trimming and evening up ther ends of broom-corn after the same has been bound together for the purpose of making brooms or brushes, and its objects 1 are to provide a machine which will have revolving cutting means and means by which the broom'which is to be trimmed may be brought into contact with the cutting means and to provide a machine by which the uneven ends of broomcorn which have been bound together may be trimmed -alike in all cases.

In the drawings, Figure lis a plan view of my invention. Fig. 2 is an enlarged side view of the revolving cutter. Fig. 3 is a vertical cross-section taken on'the line YY of Fig. 1.

Fig. 4 is a vertical cross-section onthe line X X of Fig. 1 viewed in the direction of the arrow. Fig. 5 is aj perspective view of that forni of my invention which I prefer to use in practice.4 l

1 represents the table or supportingfframe.

2 represents the supports on which the cutter-shaft is mounted.

3 is the cutter-shaft.

4 .l are shaft-bearings secured-to the sup-- ports 2.

5 is the pulley, mounted'on 4the shaft 3 to turn therewith.

6 is the cutter, which I prefer to construct with about Aseven teeth or blades, although this particular number is not essential to its successfuloperation. p

7 is the Oscillating broom-carrier.`

8 is a pivot-post-secured in the table 1.

9 is a socket provided in the under side of the broom-carrier 7 for the reception of the pivot-post 8.

10 represents a longitudinal]y-adjustable sain No. 162.159. No model.;

T bar provided with notches along one of its edges.

`1l` is a fork, between' the prongs of which the broom-handle is adapted to be placed and Vwhich fork is secured uprightly in the adjust# able bar 10 and may be made integral therewith.

12 12 are guide-pieces secured to the broomcarrier 7 and between which the notched bar 10 is loosely secured.

, .13 is a spring-actuated dog located at right angles to the notched bar, one end of which `is adapted to engage the notches of the bar 10, the other end being surrounded by a small spiral spring, which tends to keep the dog in engagement with one of the notches of the bar 10. l

14. is a bracket provided with a notch or groove for the reception of the broom-handle near its outer end. l

15, 15, and 15b represent vertical guideposts secured to the inner end of the oscillat-` ing broom-carrier.

16 representsa plate fastened to the inner edge of the broom-carrier 7 to protect the said broomfcarrier.

17 represents the broom-clamp, which will preferably be made in the form shown in Figs. 1 and 5, 17 being the handle' or operating-le ver thereof, while 1'7b and 17` are diverging branches thereof whose ends are connected by a rod or bolt 18, revolubly mounted in bearing-(brackets 19 and 19t, said bearingbrackets being rigidly secured to the broo'mcarriage 7. 17 d is a lug secured to the broom-clamp 17, whose position, when the clampy is pressed down against the broom, is between the two guide-posts l5 and 15,

\ 20 and 20'LL are stop-blocks to limit the oscillating movement of the broom-carrier 7.

21 is a metal strip secured tothe table 1 and intended to facilitate the movement of the broom-carrier 7.

22 represents a broom placed upon the oscillating carrier 7 for thepurpose of trimming off the irregular ends of the broom-corn.

In the manufacture of brooms one end of the broom-corn is secured to the lower end of the broom-handles and the free end of the IPO corn is irregular in length and requires evening before the broom is ready for use or sale.

By the use of my invention I accomplish this in the following manner: The oscillating carrier 7 is moved to the left, so that its edge strikes the stop-block 20. The clamp 17 is raised on the hinge formed by the bolt 18 and the broom is placed upon the oscillating` carrier 7, the handle thereof resting on the fork 11 and bracket 14.V The clamp 17 is th en pressed down upon the broom-corn, the irregular ends of which project beyond the edge of the plate 16. By applying power in the usual well-known way to the cutter-shaft the cutter 6 may be made to revolve. The broomcarrier 7 is then swung on its pivot 8 9 so as to bring the broom-corn ends into contact with the revolving cutter, and when said carrier has been moved until it strikes the stopblock 20 the cutter will have trimmed off the irregular ends of the broom-corn which constitute the sweeper of the. broom. By means of the movable notched bar 10 and the springactuated dog 13 the guide-fork 11 may be moved forward or backward to conform to different sizes of brooms which are'to be ably pivoted, and means for retaining the broom in xed position to the carrier, comprising a handle and diverging branches, brackets secured to the carrier, and a pivot for the branches, supported by the brackets.

2. In a broom-corn trimmer, a cutter and means for operating the cutter, a carrier suitably pivoted, guides on the carrier, a notched bar slidable between the guides, a dog for engaging the notched bar, means on the notched swing on said pivot-post and whose swinging movement is limited by the stop-blocks a bracket secured on said carrier, a notched bar mounted on said carrier and longitudinally adjustable thereon, a spring-actuated dog to engage the notches in the bar, a fork secured uprightly in said bar, a plate secured to the inner edge of the carrier, upright guideposts 15, 15 and 15b, brackets 19 and 19a means for holding the broom in place on the movable carrier.

In witness whereof I have hereunto set my hand, this 1st day of April, 1902, in the presence of two witnesses.
